An anonymous reader writes: There are a lot of 3D printers in market today. Some are capable of making prosthetics, some can make car bodies and some can even make buildings (concept). Besides all these there is a 3D Printing Pen called 3Doodler. It is the world’s first and only pen that lets you write or draw anything in the air literally. You can bring your imagination to life by drawing in three dimensions. Best thing about the pen is that it is exceptionally handy and comes for a mere $75. 3Doodler works just like a 3D printer and uses the same ‘ink’ that is ABS plastic. No computer program or software is used, just a plug-in the socket will do it all.
